Cold heading is a processing method that uses external force to change the volume or shape of the metal using a die to obtain the desired part or blank.
Many fasteners, screws and nuts are made by cold heading die forming method. Since tungsten carbide cold heading dies work under wear-resistant conditions that are subject to impact or strong impact,
Carbide is required to have good impact toughness, fracture toughness, fatigue strength, bending strength and good wear resistance.
